Solution

  1. The ear pinna (outer ear) is made up of a thin plate of elastic cartilage and is connected to the surrounding parts by ligaments and muscles. This elastic cartilage gives support and maintains the shape of pinna.
  2. The nose tip is made up of elastic cartilage. However, several bones and cartilage make up the bony cartilaginous framework of the nose.
    Hence, even though the tip of the nose is made up of elastic cartilage, it cannot be twisted like the ear pinna due to the presence of a bony-cartilaginous framework.
  Is there an error in this question or solution?
